Tumors can be damaging to surrounding blood vessels and tissues even if they re benign. If they re malignant, they re aggressive and sneaky, and often irrevocably damaging. In the latter case, early detection is key to treatment and recovery. But such detection can sometimes require advanced imaging technology, beyond what is available commercially today.
For instance, some tumors occur deep inside organs and tissues, covered by a mucosal layer, which makes it difficult for scientists to directly observe them with standard methods like endoscopy (which inserts a small camera into a patient s body via a thin tube) or reach them during biopsies. In particular, gastrointestinal stromal tumors (GISTs) typically found in the stomach and the s
An “anti-infection” machine sprays disinfectant at the entrance of Yoyogi National Gymnasium in Tokyo in November. (Pool)
Reporters, athletes and spectators stood in front of an antiseptic-spray machine as an odorless mist softly stroked their faces and hands and possibly poisoned their bodies.
The push-button equipment was set up at the entrance of Yoyogi National Gymnasium in Tokyo in November, when an international gymnastics event was held.
Although the spray, released from four points, was intended to kill the novel coronavirus, it may have done more harm than good.
“Chemicals that are effective for viruses may also have an impact on people’s bodies,” said Itsuko Horiguchi, a professor of risk communication and public health at Tokyo University of Science. “Mist in the atmosphere could result in people ingesting chemicals without eliminating the dangers.”

Porphyrins are interesting drug delivery vehicles that can specifically accumulate in cancer cells. However, how the structure of the drug-conjugated porphyrin affects its ability to penetrate and accumulate within cancer cells is not well understood.
Researchers from the Tokyo University of Science now investigate the correlation between the structure and tumour accumulation of porphyrin derivatives. Their findings can help to optimize drug delivery, possibly advancing cancer treatment.

The main culprit in cancer is healthy cells that have gone rogue and acquire the ability to divide uncontrollably. These cells acquire growth advantages over normal cells and manipulate their environment by altering the cellular pathways involved in growth and metabolism.

Niigata, Japan - Researchers from the Graduate School of Science and Technology at Niigata University, Japan along with their collaborators from Tokyo University of Science (Japan), Yamagata University (Japan) and University of Regensburg (Germany) have published a scientific article which enhances clarity on the understanding of proton conduction mechanism in protic ionic liquids. The findings which were recently published in The Journal of Physical Chemistry B sheds light on the transport of hydrogen ions in these liquids, which opens new avenues for the development of novel energy generation and storage devices.
With an objective to understand the underlying ion transport mechanism in protic and pseudo-protic ionic liquids, the multinational research team has been on constant pursuit for over a decade to uncover the mystery. We are fascinated by the immense potential exhibited by proton conducting ionic liquids. These superionic liquids are usually
